, Q1: In SDLC 1 scenario, which phase/action best describes: requirement feasibility, SRS creation,
and stakeholder sign-off for D278 project 1?
A. Planning & Requirements Analysis phase creates SRS and feasibility study
B. Design creates architecture diagrams
C. Deployment moves to production
D. Maintenance fixes bugs post-release
Correct Answer: A
Rationale: Correct answer is A. This SDLC concept is essential for D278 Scripting and Programming Foundations. For
question 1, the correct choice reflects industry standard definitions: SDLC phases sequence, Agile values individuals over
processes and embraces change, testing pyramid emphasizes many fast unit tests with pytest, integration uses
Postman/Selenium, Git uses distributed version control with add/commit/push/pull/fetch/merge workflow, and IDEs
provide IntelliSense, debugging, linting, venv isolation. The distractors confuse similar concepts: Waterfall rigidity vs Agile
flexibility, unit vs system vs UAT, fetch vs pull, or staging vs commit. Mastery ensures A+ performance on 2026/2027 OA
and real-world readiness. Hands-on practice with Git branching, writing unit tests, and using debugger will solidify
understanding and prevent common misconceptions noted in WGU materials.
Q2: Agile principle 2: How does Scrum handle changing requirements differently than Waterfall in
WGU D278 context case 2?
A. Waterfall welcomes late changes easily
B. Agile welcomes late changes via iterations, Waterfall freezes requirements
C. Agile never allows changes
D. Both require no documentation
Correct Answer: B
Rationale: Correct answer is B. This Agile concept is essential for D278 Scripting and Programming Foundations. For
question 2, the correct choice reflects industry standard definitions: SDLC phases sequence, Agile values individuals over

and real-world readiness. Hands-on practice with Git branching, writing unit tests, and using debugger will solidify
understanding and prevent common misconceptions noted in WGU materials.
Q3: Testing level 3: You need to verify interaction between Python module A and database
module B without testing entire system. What test level is this (case 3)?
A. Unit testing isolates single function
B. System testing tests complete system
C. Integration testing verifies module interactions using stubs/drivers
D. UAT validates user business needs
Correct Answer: C
Rationale: Correct answer is C. This Testing concept is essential for D278 Scripting and Programming Foundations. For
